There will be a more in-depth description, but this will have to do for now.
To start a game, you have to have a premise (any background info neccessary for starting the storyline), and a few characters, played by different people. You should have more than one character, but its more fun to play with multiple people. You'll need to have the general story planned out. Meaning that you'll need to have a short premise, a main goal, and ideas as to what the party of people could encounter. You make up whatever you like, as long as its realistic and you dont slaughter people constantly. Thats not fun. There will be more in-depth descriptions to come, and registration will soon follow.
